John McCain and Lindsey Graham have been anti-Trump from the get go, but McCain took things a little too far this morning when he betrayed the president following heated phone call to the Australian Prime Minister on Wednesday.

President Trump and P.M. Malcolm Turnbull reportedly had a heated discussion over the refugee policy between the two nations, which ended with Trump allegedly hanging up on the Australian leader, according to the Washington Post. But rather than stand by our president and trust in his leadership, McStain went behind Trump’s back and called Australia’s ambassador to undermine Trump and express his support for the nation.

Sen. John McCain (R-Ariz.) said Thursday that he spoke to the Australian ambassador to express support for the nations’ relationship after a heated call from President Trump.

“I called Australia’s Ambassador to the United States this morning to express my unwavering support for the U.S.-Australia alliance,” McCain, who’s frequently criticized Trump, said in a statement.

McCain added that he asked Joe Hockey, the Australian ambassador to the U.S., to “convey to the people of Australia” that Americans value their alliance, “honor the sacrifice of the Australians who have served and are serving by our side, and remain committed to the safer, freer, and better world that Australia does far more than its fair share to protect and promote.”

McStain, along with South Carolina Senator Lindsey Graham, have been staunch opponents to President Trump’s moratorium on travel to seven nations in the Middle East and even went on national television to express their anger. The pair worked hard to ensure that Trump never made it to the White House, and now that he’s there it appears as if they’re going to be working hard to undermine his presidency whenever they can.

With any kind of luck, both of them will be voted out of office the next time they’re up for re-election, since it’s evident they’re not working on behalf of the Americans who voted them, along with Trump, into office, but instead for their own interests.
